Dissolution Phenomena of CaO-SiO2-H2O Gel at Ca/Si>1 Coexisting with Ettringite System.

Ab InitioCalculations for the Substitutions of Al(OH)-4and SO2-4with Si Tetrahedra

“…A dissolution study of C-S-H gel coexisting with AFt system has been described without considering the interaction, especially in the theoretical part in our previous study. 15) Further investigation is necessary to describe explicit dissolution phenomena of the same system while considering the interaction between C-S-H gel and AFt. The interaction phenomena are essentially required to model the long-term dissolution phenomena of C-S-H gel, especially for the possible substitution of Si tetrahedra with Al(OH) − 4 and SO 2− 4 in the real cementitious system.…”
